After many eons of contemplation I have finally decided to model Grassington as per John Hinson's 1950 version drawn 13/10/11. I have completed the Templot templates and the baseboards. During the next, track laying, stage I wish to make sure that I can signal and interlock the layout mechanically. So far I believe I can cover most of the interlocking as I have ready many books including but not limited to the following; IRSE Green Books, "Trax 3" Signalling and Lever Frames by Jeff Geary and have downloaded Sigscribe 4 by Modratec. Each source is helpful. However, I always come to a halt when I get to lever 16 - the shunt signal from the Shunting Line to either Up Platform or Down Platform. If someone has the whole interlocking table I would be glad of a copy otherwise the bit that covers the above two routes would be most helpful.

Sorry, 16 reads to either the Up or the Down Platform. I cannot get myself in a position to see how it can do the "either" selection. My understanding is that for 16 to read to the Up platform 13 must be reversed but it must then lock 11 normal. However to read to the Down platform 13 must be reversed, 11 must be reversed and 10 must be reversed. This means 16 has to be able to lock 11 both ways but in these positions 16 can be cleared because 13 is reversed and 11 is reversed, then what do i use to lock 10 reversed, if I use 10 to lock 11 reversed then I can't use 11 normal with 10 reversed. I can see a situation where I can clear 16 when there is no safe path. Now I'm getting confused again.

Yes probably. On a more general note, and given the unusually complete signalling for the MR (but it was a later installation and possibly paid for by the Yorkshire Dales Railway Company) I'm surprised there was no signal reading from the shunting line to the goods yard and given that, were 15 and 16 yellow, perhaps in later years. And I can't find 22 on Johns' diagram
